Hi ,

I am trying to trace a perticular user sessions using a logon trigger. This works fine if I connect to the database without tns alis. Example : sqlplus scott/tiger

But no trace file is generating when I connect to the database using TNS Alias.
Example: sqlplus scott/tiger_at_orcl

we are using Oracle9i Enterprise Edition Release 9.2.0.6.0 and the database is running on Shared server mode.

user_dump_dest is already set. Please suggest.

Thanks,
